Alcoholism and Alcohol Abuse
Also called: Alcohol dependence
For most adults, moderate alcohol use is probably not harmful. However, about 18 million adult Americans have an alcohol use disorder (AUD). This means that their drinking causes distress and harm. It includes alcoholism and alcohol abuse.
Alcoholism, or alcohol dependence, is a disease that causes
- Craving - a strong need to drink
- Loss of control - not being able to stop drinking once you've started
- Physical dependence - withdrawal symptoms
- Tolerance - the need to drink more alcohol to feel the same effect
With alcohol abuse, you are not physically dependent, but you still have a serious problem. The drinking may cause problems at home, work, or school. It may cause you to put yourself in dangerous situations, or lead to legal or social problems.
Another common problem is binge drinking. It is drinking about five or more drinks in two hours for men. For women, it is about four or more drinks in two hours.
Too much alcohol is dangerous. Heavy drinking can increase the risk of certain cancers. It can cause damage to the liver, brain, and other organs. Drinking during pregnancy can harm your baby. Alcohol also increases the risk of death from car crashes, injuries, homicide, and suicide.
You may have an AUD if you can answer yes to two or more of these questions:
In the past year, have you
- Ended up drinking more or for a longer time than you had planned to?
- Wanted to cut down or stop drinking, or tried to, but couldn't?
- Spent a lot of your time drinking, or recovering from drinking?
- Felt a strong need to drink?
- Found that drinking - or being sick from drinking - often interfered with your family life, job, or school?
- Kept drinking even though it was causing trouble with your family or friends?
- Given up or cut back on activities that you enjoyed just so you could drink?
- Gotten into dangerous situations while drinking or after drinking? Some examples are driving drunk and having unsafe sex.
- Kept drinking even though it was making you feel depressed or anxious? Or when it was adding to another health problem?
- Had to drink more and more to feel the effects of the alcohol?
- Had withdrawal symptoms when the alcohol was wearing off? They include trouble sleeping, shakiness, irritability, anxiety, depression, restlessness, nausea, and sweating. In severe cases, you could have a fever, seizures, or hallucinations.
If you have any of these symptoms, your drinking may already be a cause for concern. The more symptoms you have, the more serious the problem is. If you think you might have an AUD, see your health care provider for an evaluation. Your provider can help make a treatment plan, prescribe medicines, and if needed, give you treatment referrals.

Delirium is a condition that features rapidly changing mental states. It causes confusion and changes in behavior. Besides falling in and out of consciousness, there may be problems with
- Attention and awareness
- Thinking and memory
- Muscle control
- Sleeping and waking
Causes of delirium include medications, poisoning, serious illnesses or infections, and severe pain. It can also be part of some mental illnesses or dementia.
Delirium and dementia have similar symptoms, so it can be hard to tell them apart. They can also occur together. Delirium starts suddenly and can cause hallucinations. The symptoms may get better or worse, and can last for hours or weeks. On the other hand, dementia develops slowly and does not cause hallucinations. The symptoms are stable, and may last for months or years.
Delirium tremens is a serious type of alcohol withdrawal syndrome. It usually happens to people who stop drinking after years of alcohol abuse.
People with delirium often, though not always, make a full recovery after their underlying illness is treated.

Alcohol use disorder Alcohol use disorder is a diagnosis made when an individual has severe problems related to drinking alcohol. Alcohol use disorder can cause major health, social, and economic problems, and can endanger affected individuals and others through behaviors prompted by impaired decision-making and lowered inhibitions, such as aggression, unprotected sex, or driving while intoxicated.Alcohol use disorder is a broad diagnosis that encompasses several commonly used terms describing problems with drinking. It includes alcoholism, also called alcohol addiction, which is a long-lasting (chronic) condition characterized by a powerful, compulsive urge to drink alcohol and the inability to stop drinking after starting. In addition to alcoholism, alcohol use disorder includes alcohol abuse, which involves problem drinking without addiction.Habitual excessive use of alcohol changes the chemistry of the brain and leads to tolerance, which means that over time the amount of alcohol ingested needs to be increased to achieve the same effect. Long-term excessive use of alcohol may also produce dependence, which means that when people stop drinking, they have physical and psychological symptoms of withdrawal, such as sleep problems, irritability, jumpiness, shakiness, restlessness, headache, nausea, sweating, anxiety, and depression. In severe cases, agitation, fever, seizures, and hallucinations can occur; this pattern of severe withdrawal symptoms is called delirium tremens.The heavy drinking that often occurs in alcohol use disorder, and can also occur in short-term episodes called binge drinking, can lead to a life-threatening overdose known as alcohol poisoning. Alcohol poisoning occurs when a large quantity of alcohol consumed over a short time causes problems with breathing, heart rate, body temperature, and the gag reflex. Signs and symptoms can include vomiting, choking, confusion, slow or irregular breathing, pale or blue-tinged skin, seizures, a low body temperature, a toxic buildup of substances called ketones in the blood (alcoholic ketoacidosis), and passing out (unconsciousness). Coma, brain damage, and death can occur if alcohol poisoning is not treated immediately.Chronic heavy alcohol use can also cause long-term problems affecting many organs and systems of the body. These health problems include irreversible liver disease (cirrhosis), inflammation of the pancreas (pancreatitis), brain dysfunction (encephalopathy), nerve damage (neuropathy), high blood pressure (hypertension), stroke, weakening of the heart muscle (cardiomyopathy), irregular heartbeats (arrhythmia), and immune system problems. Long-term overuse of alcohol also increases the risk of certain cancers, including cancers of the mouth, throat, esophagus, liver, and breast. Alcohol use in pregnant women can cause birth defects and fetal alcohol syndrome, which can lead to lifelong physical and behavioral problems in the affected child.
